Customer Empathy Map
Now that you have a rough sketch of what your ideal customer looks like, you have sufficient direction to take this outline and flesh out a deeper, more useful persona.
The exercise that will help to best achieve this goal is called the customer empathy map. True to its name, this exercise will force you to empathize with your customers on a deep level in order build out a robust profile of what they experience and feel on a daily basis.
Whereas the MVP only asked about your audience in rough terms, the customer empathy map helps drill down specific, categorical insights into the thoughts and feelings of your ideal customer.
Depending on the variability of your audience, you might need to complete more than one empathy map.
